Problems solved by technology

[0007] The internal grapple-type quick-opening mechanism of the explosion-proof high-voltage power distribution device disclosed in this patent document can realize the rapid opening and closing of the flameproof cabinet door, but its structure is quite complicated. It is prone to wear and tear, so that when the movable hinge is turned, it is difficult to transfer the bottom surface of the movable hinge to the working plane of the lifting transfer platform. The body is disengaged, resulting in a decrease in the success rate of opening the door and poor stability in opening the door

Abstract

The invention discloses a door opening device, and belongs to the technical field of storage equipment. The door opening device comprises a fixed supporting frame installed on the inner wall of a cabinet body and is characterized by further comprising a pulling strip, a rotary shaft and a lifting shaft. The lower end of the pulling strip is sleeved with a guide fixing block fixed to the inner wall of the cabinet body, and the upper end of the pulling strip is provided with a fixed shaft in a penetrating mode. The fixed shaft is sleeved with a fixed cover fixed to the outer wall of the cabinet body, and a reset spring is arranged in the fixed cover and arranged on the fixed shaft in a sleeving mode. The pulling strip is connected with a supporting rod. One end of the rotary shaft is rotationally connected with the fixed supporting frame, and the other end of the rotary shaft is connected with the vertically arranged lifting shaft. The supporting rod is located on the inner side of an included angle formed by the rotary shaft and the lifting shaft. The door opening device has the characteristics of being simple in structure, low in manufacturing and maintenance cost, high in door opening success rate and good in use stability.

Description

technical field [0001] The invention relates to the technical field of storage equipment, in particular to a door opening device suitable for lockers. Background technique [0002] Lockers are generally divided into family lockers and business lockers, which are mainly used to facilitate people's use, store different items, and classify them. For families or dormitories with less space, it is a must-have item. It can make full use of the space to accommodate more daily items, and it can also well decorate people's home environment. [0003] Lockers are widely used in offices, factories and other types of small parts, samples, molds, tools, electronic components, documents, design drawings, bills, catalogs, forms and other storage management. The locker is made of high-quality cold-rolled steel plate. Compared with the traditional wooden cabinet, it is not easy to be damaged, resistant to impact, and it is not easy to breed bacteria and produce peculiar smell. Therefore, the...
